(1)0.27+0.27×0.37+0.27×0.63
=0.27×(1+0.37+0.63)
=0.27×2
=0.54
(2)12.5×4×2.5×16
=(12.5×8×2)×(4×2.5)
=200×10
=2000
(3)9.68×101
=9.68×(100+1)
=9.68×100+9.68
=968+9.68
=977.68
(4)9.6÷(9.6×4)
=9.6÷9.6÷4
=1÷4
=0.25
(5)0.78÷0.25÷4
=0.78÷(0.25×4)
=0.78÷1
=0.78
=0.27×(1+0.37+0.63)
=0.27×2
=0.54
(2)12.5×4×2.5×16
=(12.5×8×2)×(4×2.5)
=200×10
=2000
(3)9.68×101
=9.68×(100+1)
=9.68×100+9.68
=968+9.68
=977.68
(4)9.6÷(9.6×4)
=9.6÷9.6÷4
=1÷4
=0.25
(5)0.78÷0.25÷4
=0.78÷(0.25×4)
=0.78÷1
=0.78
